In the process of doing my research over the
past 25 years, I have developed several scales that may be useful to
other researchers. Some of these scales have been used many times and
have a good deal of evidence to support their validity and usefulness.
Others have been used only a few times but have nonetheless performed
well.

These scales may be used for research purposes without permission. If
you use a scale in your research, please cite the original source of
the scale listed below.

Interaction Anxiousness Scale

Note: This article describes two scales, the Interaction
Anxiousness Scale and the Audience Anxiousness Scale. However, only the
Interaction Anxiousness Scale has received widespread use and has a
body of data to support its validity (see Leary, M. R., & Kowalski,
R. M. [1993]. The Interaction Anxiousness Scale: Construct and
criterion-related validity. Journal
of Personality Assessment, 61, 136-146.) Thus, at present, I can
recommend the Interaction Anxiousness Scale but can not attest to the
merits of the Audience Anxiousness Scale. (Fortunately, there are other
good measures of audience anxiety, speech anxiety, and stage fright
available.)
